Definitions
- the invention relates to a closure cap for the sterilization or aseptic filling of medical articles, in particular for the sterilization of dialyzers and treatment sets for dialysis.
- the invention relates to a medical article with a fluid connection and a closure cap according to the invention.
- Medical articles such as dialyzers and treatment sets, tube sets for dialysis and in particular for extracorporeal blood treatment are used in the treatment of patients in various therapies.
- a prerequisite for the use of such medical articles in the treatment of patients is in particular their sterility.
- such medical articles are subjected to a heat sterilization process, in particular a steam sterilization process or a sterilization process with a sterilizing gas, such as ethylene oxide.
- a sterilizing gas such as ethylene oxide.
- the fluid connections of the dialyzers are closed with closure caps during production after, for example, rinsing and sterilization steps have been carried out.
- Inline steam sterilization has become particularly popular for the sterilization of dialyzers in the interests of efficient industrial production, as described in various versions, e.g. in the European patent application EP 0 427 055 A2 and the international patent application WO 2018/104498 A9.
- dialyzers In “inline” steam sterilization, manufactured dialyzers are clamped to a rinsing and sterilization device via the liquid connections. The dialyzers are then rinsed in several rinsing steps with, for example, water via the blood connections and the dialysate connections of the dialyzer. This process flushes unwanted residues from the production of the dialyzers, such as particles, residual solvents or residual polymers, from the interior of the dialyzer.
- the dialyzer is usually sterilized using superheated steam, for example at 121°C. For this purpose, the superheated steam is passed over the blood and/or or dialysate connections into the interior of the dialyzer, thus sterilizing the interior of the dialyzer.
- closure caps have been developed with which a dialyzer is connected to the rinsing and sterilization device via the blood and dialysate connections in a fluid- and germ-tight manner and which are functionally designed to close the blood and dialysate connections when the dialyzer is removed from the rinsing and sterilization device.
- closure caps for fluid connections of medical articles are also useful in order to be able to close the medical article again after use in a therapeutic procedure.
- the dialyzer may still be partially filled with treatment fluid and/or blood.
- dialyzers usually have two liquid connections for blood.
